Badger Fast-Blast Jar Adapter Issue
Posted by PeterM on Tuesday, April 23, 2019 2:27 PM
I just bought my first airbrush, a Badger 200, and I am having an issue with the Fast-Blast Jar Adapter (plastic type, 50-208) that I also bought.

On the topside of the adapter cover there is a gasket. The gasket is located between the cover’s outer top surface and a plastic type elbow, which angles the flow tube 30 degree.  My issue is that paint is leaking around the gasket enough that I had to stop and clean up.
I mixed the enamel paint per Donn Yost’s method and the pressure is set at 32 PSI.
 Is this normal? Has anyone else experienced this with their badger adapter or any other brands caps?

Are you sure that paint is leaking from the gasket?  There is a small hole on the adapter to allow air in during spraying.  Could the leak be coming from there?  I have had some paint leak through the hole in the adapter while painting by moving the air brush into angles not really normal for spraying.  Is the jar tight against the gasket?  If the jar is tight against the apadter head, the gasket might be too thin to seal properly.  Increase the thickness if you can by adding another layer of gasket or make one that will seal the jar better.  I don't think that airbrush pressure or the mixing of paint is causing any of your issues.

I had to google this item to see what it is. I also use a Badger 200, been using the same one for 40 years, but I wasn't familiar with the Fast Blast Jar Adaptor.

I have a couple questions regarding this item; 1) Is the plastic tube which passes through the cap a one piece tube, or is it two tubes joined inside the plastic elbow portion? 2) How is the gasket tightened? Does the elbow piece screw into the lid to tighten the gasket?

If the tube is one piece then no leaking should ocurr through the gasket. If the tube has a split where it passes through the elbow (or a two piece tube of which the pieces are connected at the elbow) may potentially leak when the trigger is released if the gasket's seal is conmpromised. When I look at photos online it looks as though there is no real squeeze on the gasket, but its hard to tell. As Mike said, painting pressure or mixing qualities should not cause leak issues.

1) Is the plastic tube which passes through the cap a one piece tube, or is it two tubes joined inside the plastic elbow portion? ANS: It looks like two tubes; therefore the elbow inner chamber must be filling up with paint. It is leaking between the sealing surface of the top-cap and the gasket and a little from the gasket to the elbow surface. Also, it is not leaking from the breather hole or from the cap threads to the glass jar. 2) How is the gasket tightened? Does the elbow piece screw into the lid to tighten the gasket? ANS; the elbow has tongs which snaps onto the cap (tongs can be seen from the backside of the cap) entrapping the gasket. There is no way of further tightening it down. Question: If you are not using the FASTBLAST Jar Adaptor, then what have you been using? What I have done is using a RTV sealant around the cap/gasket/elbow surfaces as well as the backside/tong area. I made sure that the breather hole remained open. I will report back on how his worked out.

My airbrush is the older style, called the 200 IL. It uses a metal jar adaptor 50-007 with a centre threaded fitting. There is a removable metal elbow piece that fits to the airbrush body spigot with a tapered friction fit. The cap screws onto the bottom of the elbow, and a little spigot at the bottom of the elbow accepts the plastic suction tube. Later editions of the Badger 200 use the same system, but the cap is plastic (though the centre fitting that screws onto the elbow is still metal).

It certainly seems as though something is not right in the elbow area of your jar adaptor. Does the paint leak out when you release the trigger, or is it too hard to tell?How does the airbrush spray? It would seem that if there is a leak in or near the elbow, then it would suck in air when the trigger is depressed and leak paint when the trigger is released. If it is sucking air, then the airbrush should perform poorly.

Either way, something is wrong. You may have to disassemble the cap/elbow assembly to see what's up, look for places where paint could leak out. It may need to be replaced. Hopefully the RTV sealant does the trick.

Sorry guys, you were right.
 After two more tests (no model painting), the paint is coming out of the breather hole.  During both tests the two oz bottle was filled to about 80%. When I kept the bottle level I noticed the paint was splashes around in the bottle and some paint would spit out a little from the hole. The first time, I was spray a model and the paint must have had hit the edge of the gasket making it look like it was leaking.
Is spitting from the breather hole common?

Is the little round teflon head gasket in place? This is the tiny white ring that fits between the head and the airbrush body. If I'm not mistaken, a damaged or missing head gasket can cause bubbling in the paint jar, and if it is 80% full, it might possibly cause spitting out of the vent.

In normal use, air should enter through the hole (vent) to fill the space vacated by the paint being used up (sprayed). The vent is there to prevent a vacuum from forming in the jar as the paint is consumed. However, if the jar is quite full, normal airbrush motion can sometimes cause paint to be 'splashed' out of the vent, but otherwise, air should only enter through it. No spitting out of it should occur.
